According to the UN Food and Agriculture Organization (FAO), the technology used to spray pesticides in most developing countries reflects technical standards of 40 years ago, resulting in pesticide waste and environmental damage. FAO called for the adoption of minimum standards for the safe and efficient application of agrochemicals through good quality equipment and better training of farmers. According to FAO, farmers and equipment operators have insufficient knowledge about pesticides and correct methods of application. Extension services rarely have technicians with any specialized knowledge of application technology .In many countries the only specialist offering advice to farmers on application technology, handling and calibration of their equipment are the representatives of pesticides companies. Many farmers mistakenly believe that high volumes, high pressure and high doses, are the most appropriate way to apply pesticides. In addition, in many countries, much of the spraying equipment is in extremely poor condition with worn-out sprayer nozzles not being replaced, or worse, enlarged deliberately to achieve higher flow rates. FAO has developed Guidelines for the basic requirements for pesticide application equipment and Standards for pesticide application equipment which includes test procedures. They suggest that incentives for improved equipment quality should be created. A certification system could be introduced on a voluntary basis by manufacturers using the certificate as a quality trade mark and for sales promotion. Working with small groups of trainers, practical training of farmers and operators should be introduced. FAO do organize regional workshops to create awareness among governments, farmers and the commercial sector.
